Thanks for the thread! I did end up getting the boat for a steal ($7,500 back in 2009 with less than 175 hours on it) and it has been an absolute blast! I picked up a performance impeller today, but as noted the Merc engines get much less love on the Seadoo forums than the Rotax. I appreciate any help specific to the carb Merc engine though!

Cheers,

Justin
